func main() {
    // Create a buffer to write our archive to.
    buf := new(bytes.Buffer)

    // Create a new zip archive.
    w := zip.NewWriter(buf)

    // Add some files to the archive.
    var files = []struct {
        Name, Body string
    }{
        {"readme.txt", "This archive contains some text files."},

    }
    for _, file := range files {
        f, err := w.Create(file.Name)
        if err != nil {
            log.Fatal(err)
        }
        _, err = f.Write([]byte(file.Body))
        if err != nil {
            log.Fatal(err)
        }
    }

    // Make sure to check the error on Close.
    err := w.Close()
    if err != nil {
        log.Fatal(err)
    }
}
